Title: An audio amplifier with a controllable split supply for the output stage
Inventor: LESSO JOHN PAUL
IPC: H02M3/07
Filed: 2006-12-22
Abstract: The power supply 80 for an audio amplifier output stage 40 provides voltages which vary in dependence on a volume control signal S2 which controls the gain of amplifier stage 20. The power supply comprises a flying capacitor charge pump circuit (figures 5b, 16b) which provides opposite polarity supplies from a single polarity input. The charge pump may be fed through a controllable DC-DC buck converter (1010, figure 26), which can be bypassed when the battery voltage is low. The supply voltages may be regulated (figure 15). The charge pump may have dual modes (figures 10, 16b) wherein it can be controlled to provide outputs which are either equal to the input voltage or a fraction of the input voltage. Only one flying capacitor is required to provide a split supply of +/- VDD/2.

Title: Channel management for a digital audio/video receiver
Inventor: HILL-JOWETT DAVID RICHARD
IPC: H04H60/23
Filed: 2012-05-04
Abstract: An audio/video content receiver is configured to receive media via a broadcast data path, the media content being arranged as a plurality of media channels. The receiver comprises a host module (e.g. a TV or set-top box / STB) having a tuner configured to assign channel numbers to the media channels to allow selection, at the host module, of one or more of the media channels for reproduction. The host module is able to store channel association data which relates the channel numbers to the received media channels. The receiver also comprises a removable conditional access module (CAM) which has an access control unit for decoding access-controlled encoded broadcast content, the host module and the removable CAM being arranged to provide an encrypted communication link for decoded access-controlled encoded broadcast content between the conditional access module and the host module. The host module is configured to acquire 1st channel association data in the form of a first network information table (NIT) via the broadcast data path and 2nd channel association data in the form of a second NIT from the CAM. The host module determines 310 whether conflict exists between the 1st and 2nd channel association data. If such conflict is detected, unused channel numbers are identified 330 and the CAM is configured to select 350 one of the unused channel numbers for use by a received media channel for which the detected conflict exists. Conflict between 1st and 2nd channel association data is determined by merging or combining 300 the 1st and 2nd NITs and identifying those channel numbers for which multiple media channels have been assigned. The receiver and associated method enable the management of channel data when channel allocation conflict exists.

Patent GB-2507315-A (GB)
Title: Authentication of messages using dynamic tokens
Inventor: BLAIR CHRISTOPHER DOUGLAS
IPC: G06F21/30
Filed: 2012-10-25
Abstract: A system and method are described whereby a message (e.g. email, SMS etc.) can be readily determined to be from an authorised sender or, conversely, identified as being from an imposter. The arrangement does not rely on conventional encryption and/or digital signature schemes, and instead allows the human recipient readily to identify fraudulent messages by recognizing whether or not a digital token associated with a received message complies with one or more pre-determined rules, even if the system presenting the message is unaware of said rules or even of the authentication process as a whole. The rules are rules known to the authorised sender and the recipient user, such as wherein a user has registered with the authorised sender previously and pre-selected one or more rules that the token should comply with in order to be received as a compliant token. For example, the user may specify one or more rules the token should comply with such as including particular word sequences, characters, upper-case/lower-case relationships, order, position, orientation, presence, colour, font, style, appearance, format etc. This allows a user, for the embodiment of a visual token, to receive a message with an attached token and to visually inspect the token to determine that the one or more specified rules have been complied with. The rules allow a different token to be used each time an email is sent by the sender (i.e. provide for a dynamic token) compared to typical methods which rely on a static password, picture etc. to provide a sender with a means to indicate that it is from the purported sender. One embodiment allows a bank to send an email to a recipient and easily allow the recipient to see that the email is from the bank, or conversely identify a phishing message. The token may be based on text, characters, pictures, audio, moving images, movements, haptic gestures, smell/odours etc.

Title: A flexible door
Inventor: MOLONEY THOMAS PATRICK
IPC: E05D3/08
Filed: 2013-04-23
Abstract: A flexible door has a main door structure 10 and a fixing and hinging arrangement 22 for securing the main door structure to a door frame. The fixing and hinging arrangement is adapted to allow hinged movement of the main door between a closed and an at least partially open position. The main door further comprises at least a resilient support member 12 adapted to allow the door to bend through a bend radius when an opening force is imparted on the door. The support member may be formed from a polycarbonate material. The resilience of the support member may be such that below a threshold opening force the resilient support member, and hence the door, will bend without any movement occurring at the hinge arrangement. Opening forces beyond this will additionally cause movement of the hinge (fig 8). The door may also include a hinge guard 24.
